Petunia plant named ‘Sunsurfmictrout’

ABSTRACT

A new and distinct cultivar of  Petunia  plant named ‘Sunsurfmictrout’, characterized by its outwardly spreading and mounding plant habit; vigorous growth habit; freely branching and flowering plant habit; long flowering period; and medium-sized light red-colored flowers.

Botanical designation: Petunia×hybrida.

Cultivar denomination: ‘Sunsurfmictrout’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia, botanically known as Petunia×hybrida and hereinafter referred to by the name ‘Sunsurfmictrout’.

The new Petunia is a product of a planned breeding program conducted by the Inventors in Shiga, Japan. The objective of the breeding program is to create new Petunia cultivars with attractive foliage and flower coloration.

The new Petunia originated from a cross-pollination made by the Inventors in September, 2003 in Shiga, Japan of a proprietary selection of Petunia×hybrida identified as code number PS105-3, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code number PS143-1, not patented, as the male, or pollen, parent. The new Petunia was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Shiga, Japan.

Asexual reproduction of the new Petunia by terminal cuttings in a controlled environment in Shiga, Japan since September, 2005, has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Sunsurfmictrout has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunsurfmictrout’. These characteristics in combination distinguish ‘Sunsurfmictrout’ as a new and distinct cultivar of Petunia:

-   -   1. Outwardly spreading and mounding plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching and flowering plant habit.     -   4. Long flowering period.     -   5. Medium-sized light red-colored flowers.

Plants of the new Petunia can be compared to plants of the female parent selection. Plants of the new Petunia differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Petunia are larger than plants of the         female parent selection.     -   2. Plants of the new Petunia have larger flowers than plants of         the female parent selection.

Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Petunia are more compact and mounding than         plants of the male parent selection.     -   2. Plants of the new Petunia and the male parent selection         differ in flower color as plants of the male parent selection         have light pink-colored flowers.

Plants of the new Petunia can also be compared to plants of the cultivar Sunpatire, disclosed in U.S. Plant Pat. No. 15,756. In side-by-side comparisons conducted in Shiga, Japan, plants of the new Petunia and the cultivar Sunpatire differed in the following characteristics:

-   -   1. Plants of the new Petunia were more compact than and not as         spreading as plants of the cultivar Sunpatire.     -   2. Plants of the new Petunia had smaller flowers than plants of         the cultivar Sunpatire.     -   3. Plants of the new Petunia and the cultivar Sunpatire differed         in flower color as plants of the cultivar Sunpatire had red         purple-colored flowers.
